Strategy on AWS environments assigns individual security groups for each Load Balancer (ELB/ALB) that is deployed with an environment.
If multiple environments are deployed into the same AWS VPC, each ELB within each environment will have its own Security Group.
Customers have full control over the network access rules associated with the Security Group and can tailor the access based on their security requirements.
To manage the ingress/egress rules for the Load Balancer Security Group, refer Configure Security Group by AWS.
